Abstract
A track guiding apparatus (10) for guiding the track links (22) of a moving undercarriage system (12) of a track-type vehicle having a track roller frame (18) and a plurality of track rollers (20) includes a support bracket assembly (14) secured to the roller frame (18) and a plurality of guide bars (16) secured to the support bracket assembly (14). Each of the guide bars (16) has a contact surface (50, 52) adapted to contact a hardened rail portion (56) of the track links (22) when the links (22) are moved laterally. The track guiding apparatus (10) prevents de-railing of the track links (22) from the track rollers (20) due to irregular ground conditions or when foreign material becomes lodged between the rollers (20) and the links (22).
